Flexible couplings, as the name suggests, are designed to accommodate misalignment, vibration, and shock loads between connected components. Rigid couplings, in contrast to flexible couplings, provide a fixed and non-yielding connection between shafts. They are typically made of solid materials such as metal or composite and transmit torque without any flexibility.
Torque Capacity – Flexible Coupling is Lower torque capacity while Rigid Coupling is higher torque capacity
Alignment – Flexible Coupling is Compensates for misalignment while Rigid Coupling requires precise alignment
